If your wave machine has the new style Rotary Chip Wave and the Hot Air De-Bridging Knife options you can expect good yields. However, depending on the PCB design, double-sided solderpaste reflow and selective solder pallets for wave solder is a bett

The ultrasonic frequency used in today�s stencil cleaners is usually a 40 kHz �sweep� frequency (also used on semiconductors and other sensitive cleaning applications). This frequency is not low enough to cause stencil damage (the lower the frequen

| Folk's, | | I'm looking for some helpful suggestions for reworking wave soldered bottomside components that have been glued. | I'm not a fan of the twist and break approach and as some of them either have a double dot or a slot configuration this

After some precursory experimentation, I am planing on employing a form of low melting temp solder for use in reworking some very dense, copper core PCB's, both SMT and THT, which were originally mounted with 63/37 solder. The main problem with the

Sign makers utilize a material called "Scotch-Cal" and "Scotch-Brite" in making decals used in outdoor environments. Material similar to this comes in metallic silver and gold. Pieces of this can be economically die-cut and affixed to your PC Board

Dear Colleagues, I am working with a new prototype product that is presenting some interesting problems. My Engineering Dept. has made some suggestions that I find a little odd. I am looking for some confirmation from fellow SMD personnel as to the

We recently had an in-house demo with the smaller IR bottom heater PACE machine. The machine was barely able to remove some components, but could not replace new ones at all. Also, the nozzle for the hot air would not fit in the tight areas of the ho
